WINDOW-SHADE STRUCTURE AND VENTILATOR THEREFOR.

Specification of Letters Patent.

PatentedMay 6, 1919.

Application filed November 13, 1918. Serial No. 262,341.

To all whom it may concern:

Be it known that I, GILBERT E. Losnn, a

citizen of the United States, residing at 1822 North Bouvier street,Philadelphia, in the county of Philadelphia and State of Penn-,

sylvania, have invented new and useful Improvements in .Window-ShadeStructures and Ventilators Therefor, of which the following is aspecification.

The invention relates to window shades or blinds, and to ventilatingdevices therefor, and has for an object, to provide a window shadestructure and ventilating device in which the shade can be operated inthe usual manner and the ventilating device operated independently ofthe shade or so arranged that the ventilatingdevice willbe inventilating or non-ventilating positions whether the shade proper be inraised or lowered thereon.

position.

I am aware that various forms of shades and window ventilating deviceshave been used heretofore, but in the majority of the instances theventilating attachment or device forms a part of-the shade or curtain,

wherein the lowering of the shade relative,

to the window sash will not expose the ventilating device or bring itinto ventilating position, whereas the continued lowering of the shadewill do so because of the fact that the ventilating structure forms anintegral part of the shade proper, or is so rigidly attached thereto, sothat when one is operated, the other must also operate. This has beenfound to be highly undesirable because when the shade is lowered to itslowermost extremity, the ventilating device must necessarily be exposed.I

In my invention I overcome these. defects by having the shade properoperated independently of the ventilating devlce although theventilating device or structure is so arranged anddisposed relative tothe window sash or shade proper that the effect to the observer is thatof a shade with an ornamental border and thus the entire structurepresents a more attractive arrangement than is ordinarily observed withthe form of shade that is now generally used in connection with thewindow sash.

In the further disclosure of the invention,

Fig. 7 is a viewof the bracket by itself, looking into the same, and--Fig. 8 is an elevation of a modified form of bracket. i

Referring more particularly to the views, the numeral 10 indicates ashade or blind, as the case may be, which is of the ordinaryconstruction made inthe same manner as the shades that are generallyemployed on window or window sashes, the mentioned shade being mountedupon a roller 11 of the usual construction and which therefore, is whatis ordinarily termed a sprin roller, the latter having the shadenormally wound thereon with the usual studs'12 of the shade rollermounted ,in'suitable brackets which will be more particularly describedhereinafter. The shade 10 also carries the usual shade cord 13, and anornamental or suitable form of ring or holder 14 whereby the shade canbe conveniently raised or lowered.

A second superposed roller 15 is employed, being similar in everyrespect to the roller 11, and therefore being provided with the usualstuds 16, this roller 15 being also of the well-known spring variety.ound upon the roller 15 and having its upper end suitably securedthereto is a ventilating curtain 17 having series of openings 18therein, which are preferably covered with the cloth or wire meshindicated by the numeral 19, provided for the purpose of excludingflies, mosquitoes, and other insects from the room.

The ventilator curtain 17 depends, as

shown in Fig. 4, to connect at its lower edge border strips or curtainsacting as a part of the ornamental fixtures of my structure, willenhance the appearance of the entire device and also prevent the generalobserver, whether he be in the room or on the outside, from seeing thelower roller 11. The inner border strip 21 has the usual cord 22 andhandle or holder 23 provided for the purpose of raising or lowering theborder and consequently also the ventilator curtain, an additional cord22, being EtttiLCllGCltO one of the border strips and the cross piece 20so as to relieve the border strips of the strain that ordinarily wouldresult when the pull is exerted upon the cord 22.

As shown in Figs. 5, 6, 7, the structure.

described is mounted upon a plurality of brackets 2&, one being providedfor each side of the sash. Each bracket is preferably formed of a singlepiece of metal to provide upper and lower bearings 25 for the studs onthe upper and lower rollers, and these hearings have lateral attachingflanges 26 through which suitable screws are passed to rigidly securethebrackets to the sides of the window sash, each bracket further includinga vertical guide portion 27, having a longitudinal slot 28 and of atriangular shape in cross-section, said guide portion beingformed'between the upper and lower bearings 25. Referring now to Figs.5, 6 it will be seen that the cross piece 20, at the ends thereof isprovided with fingers or proections 29, which are shaped to conform tothe sides of the guide portion therefore overlapping said guide portionand it will also be seen that the vertical end portions of theventilator curtain 18 will pass through theslots 28 of the guideportions and ride up and down therein as the ventilator curtain israised or lowered.

It will now be seen that when the structure described is assembled withthe lower roller journaled in the lower bearings of the brackets and theupper roller journaled in the upper bearings of the brackets, that thevertical end portions of the ventilator curtain will ride in the guideportions of the brackets, and the whole structure being disposed in thewindow sash, it will be seen that whether the ventilator curtain is innonven'-' it is desired to bring the same into ventilat-' ing'position,it is only necessary to exert a pull upon the cord and holder 22,23,'thus causing the border strips to be drawn down and resulting in theunwinding of the flexible ventilator curtain from its roller to exposethe ventilating openings thereof at the top of the window, the uppersash of which has been previously lowered so that fresh air can readilyenter the room. It should be particularly noted that by having thevertical end portions of the ventilator screen operating in the guideportions of the brackets, that the tendency of the ventilator screen toflap and be noisy is overcome, it being well-known that in the use ofthe ordinary window shade when the window is raised from the bottom orlowered from the top, the result usually is a flapping of the shade thatis decidedly an inconvenience and may result in the tearing ormutilation of the shade. With my device-this is overcome by having theventilator curtain arranged so that it would be drawn in to ventilatingposition immediately adjacent the upper part of the sash, and thus thereis less tendency of rain, sleet or snow to enter the room than therewould be if the ventilator were at the bottom ofthe sash, furtherproviding proper ventilation by having ventilating openings at the top.

In 1 ig. 8 I disclose a modified form of bracket and which is preferablyemployed in cases Where the spring roller is not of the usualconstruction involving a pawl and ratchet wheel construction, butwherein the latter is dispensed with and the spring of the rollercontinually exerts a pull to wind up the ventilator curtain thereon.Therefore the form of bracket shown in Fig. 8 and indicated by numeral27 has a plurality of opposed projections 30, formed integrally with thebody of the bracket and near the upper end ofthe guide portion, thelower end of the latter on one side being formed with a notch 31. Withthis arrangement the projecting fingers 29 will bear against and be heldby the projections 30 to prevent the ventilating device from entirelywinding up upon its roller, and when a pull is exerted on its cord tobringv the ventilator curtain down, oneof the fingers on each end of thecross piece will fit into the notch 31 on each bracket when theventilator curtain is unwound from the roller to be brought in theventilating position, and upon releasing the pull on the cord theventilator curtain will be held in this position.

From the foregoing description it will now be clearly seen that thedevice described is so arranged that the ventilator curtain can beoperated independently of the usual shade, and that the shade can beoperated independently of the ventilator curtain, although it must beremembered that a relation exists between the ventilator curtain and theshade because the border strips, forminga part of the ventilatorstructure, provide a means for inclosing the shade roller and are anecessary part of the construction in order to bring about the desiredresult and orna mentality.

By employing brackets of the character I have described, it is possibleto bring about a standard form of construction which will be applicableto various kinds of windows and which will be a commercial asset fromthe standpoint that it will not require the use of skilled labor tomount the entire de vice upon a standard form of window sash, theinvention consists of few and simple parts that can be readily assembledin proper relation to each other to bring about the desired result.

It will be understood that I do not limit myself to the particulardisclosure in the drawings and description herein; that various slightchanges may be made without departing from the spirit of the inventionand that the scope thereof is defined in the appended claims.

It will be further understood that my form of ventilating device, can beused with any form of standard shade and therefore my ventilating devicecan be applied to a. window sash which has previously been equipped witha shade, although of course it will be understood that a particular formand kind of shade can be cut for my particular kind of ventilatingdevice, if desired. However by providing a device that can be applied towindow sashes that are already equipped with shades it will be apparentthat it is only necessary to provide the ventilator curtain and thecomponent parts thereof in sizes suitable to the usual standard sizes ofwindow sashes and the shades that have been previously mounted thereon.

Having described my invention, I claim,
